sage, so as to balance the load upon the bolt. The lower pivot of the revolving structure is arranged to'slide vertically and is fitted movably to a floor-socket, and such pivot would be fitted to a supplementary socket in the new position to which the wings are moved, the wings being then held at both top andbottom, and bolts are provided upon the tops of the wings to lock them to the ceiling of the casing when adjusted to clear the passage-way.

The invention includes a brace pivoted at one end upon one of the wings and having a pivoted slide at the other and fitted movably' to the hand-rail upon the adjacent wing. The hand-rail is provided with a stop or pawl to fasten the brace in a suitable position when the wings are extended for operation, and the detachment of such pawl permits the wings to be folded by the movement of the slide upon the hand-rail.

The invention also includes an upper brace for the tops of tall wings, one end of the brace being pivoted upon one of the wings, a channel-way being fixed radially upon the adjacent wing, and the free end of the brace having a head or stud fitted movably in such channel-way. A stop or pawl movable into the channel-way serves to hold the brace extended when desired to secure the wing in an operative position. The head of the brace in its engagement with the channel-way operates substantially the same as the slide fitted movably upon the hand-rail.

The invention will be understood by reference to the annexed drawings, in which Figure 1 is a front elevation of the doorcasing with the wings in their operative position. Fig. 2 is a plan of the wings extended and secured by braces applied to the handrails. Fig. 3 shows two of the wings having the brace fitted to the hand-rail and folded parallel to one another. Fig. e is a section adjacent to the inner side of the pivot and lock plate for one of the braces, and Fig. 5 is a section of the wing and device for locking the slide. Fig. 5 is a section of a hand-rail with pawl adjacent to the slide. Figs. 3 and To (117/ whom it may concern:

Be it known that I, THEorHILUs VAN KAN- NEL, a citizen of the United States, residing at Bedford Park, county of New York, and State 5 of New York, have invented certain new and useful Improvements in Revolving Door Structures, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The present invention relates to that class of revolving door structures in which the door-wings forming the revolving portion are connected to a pivotal center pin and kingbolt and may thereforebe collapsed or folded upon one another to permit free passage through the door-casing.

The invention relates partly to the means for holding the door-wings extended at right angles to one another when in operation and partly to the means for shifting the king-bolt, with the door-wings, from the central part of the casing to furnish a freer passage through the same.

Heretofore it has been common to extend the head of the king-bolt through a slot in the ceiling of the door-casing and to swivel it upon a wheeled carriage or truck adapted to shift the bolt and door-wings to the side of the casing. I

To avoid the expense of a wheeled truck, I provide in the present invention a guide-arm having one end pivoted upon the ceiling of the door-casing and the other end provided with a roller to run upon a supporting-rail. The king-bolt is swiveled in the guide-arm adjacent to the roller, so as to be moved in a curved slot to the desired position, and is supported by a self-adjusting bearing to avoid straining the bolt. The pivot of the guide- 4 arm may be mounted in any desired relation to the center of the door-casing so as to move the bolt laterally, and thus transfer the folded wings to the side of the casing or forwardly, so as to bring one of the wings in line with the doorway to be used for temporarily closing the passage when desired. The doorwings are placed at opposite sides of the kingbolt when moving them to the side of the pasl 5 are upon a larger scale than Fig. 2, and Fig.

4 is upona still larger scale. Fig. 6 shows a part of the wings at the top with the upper brace thereon, and Fig. 7 is a plan of the same. Fig. 8 is a horizontal section of the channel-way near the top edge of the same. Fig. 9 shows the ceiling of the door-casing. Fig. 10 is a section of the segmental walls just below the ceiling with the wings shown in different positions in full-and dotted lines. Fig. 11 is a cross-section of the ceiling and guide-arm supporting the center king-bolt of the wings upon a scale twice as great as Fig. 9. Fig. 12 is a plan of the hanger-socket upon the guide-arm with the axle for the roller. Fig. 13 is a plan of the means for locking the ad justing-nut above the ball-races. Fig. 14 shows the under side of the hanger for the ball-races, and Fig. 15 an edge view of the same. Figs. 16 and 17 show alternative constructions.

The casing is shown with side segments a and ceiling Z), the king-bolt 0, which supports the wings, being extended through one end of a slot in the ceiling. In Fig. 2 the Wings d are attached rigidly together, and the wings d hinged thereto at the hinges e. Hand-rails f are shown of the usual length on two of the wings, and upon the other wings hand-railsf, extended closer than usual toward the hinge of the wing. each hand-rail and jointed to a link or brace h, which is hinged to the adjacent door by a pivot z. The hand-rails are hollow, and a pawl g is shown in Fig. 5 projected normally from within the rail to lock the slider against one ofits supports g Fig. 3 shows one of the hinged wings d folded parallel with one of the wings d, such movement of the hinged Wing operating to press the slider outwardly upon the wing (Z and to draw the slider inwardly upon the wing cl. The handrails serve as guide-bars for the free ends of the braces h, and any means of locking the slide thereon serves to hold the brace extended to secure the hinged wing d firmly in an operative position. Figs. 4 and 5 show another means for locking the slider in a sliding bolt 70, fitted movably in the foot-plate of the pivot v at right angles to the guide-bar or hand-rail upon the opposite side of the wing. A spring is shown fitted to notches Z in the side of the bolt to restrain it from movement when set in an operative or inoperative position. Fig. 4 shows the bolt set in contact with the hand-rail, so as to lock the slider against a stop on upon the hand-rail. Such stop is formed as a bearing fixed to the door-wing, as shown in Fig. 1, to sustain the hand-rail at the middle of its length, where it supports the thrust of the brace. The use of such braces permits the hinged wings to be instantly released and thrown into their inoperative position, where they may be secured by any suitable means.

The upper brace, as shown in 1, 6,

A slider g is fitted movably to closing the passage-way.

casing is shown hinged, so as to be shifted in wardly against the remaining wings to pre-v vent the movement of air through the casing" and 7, consists of a link it, pivoted upon one of the wings, similarly to the brace 7i, and hav ing a projection or stud 11. upon its free end adapted to fit in a channel-Way 0 upon the adjacent wing. The channel-way is formed with an outer rib 0, which holds the studm. movably, and a set-screw p is shown at one end of the channel-way to arrest the stud or head of the link when the hinged wing is operatively adjusted. A portion of the rib 0 is removed adjacent to the set-screw, and a pawl r is mounted upon a spindle s to fill the place of such rib and to be turned into the channel-way when desired, as shown in Fig. 7. When in such position, the pawl locks the stud or head of the link it against the setscrew and holds the attached wing rigidly. The spindle s is shown in Fig. 1 extended downward through a bearing .9 upon the face of the hinged wing and provided with a handle Z for turning the pawl, so that it may be withdrawn from the channel-way, as shown in Fig. 8, which permits the hinged doorwing to be folded.

It is obvious that the bolt is and the slider g perform the same functions for the head of the brace as the pawl r and stud n, and the bolt is may therefore for the purposes of this invention be termed a pawl and is included in the generic term pawl where used in the claims as a means for holding the head of the brace. The retraction of the bolt and the turning of the pawl occupy only a moments time, and thus set the-upper and lower parts of the hinged wing free to be turned to an inoperative position.

Fig. 10 shows an old construction for the door-wings, illustrated in Van Kannels patent, N 0. 656,062, granted August 14, 1900, for a revolving door, by which all the wings may, if desired, be folded together at one side of the post. The dotted lines (Z (Z cl d show the operative position of the wings, and they are also shown in dotted lines folded together in the center of the passage. show the means for shifting the king-bolt when the doors are thus turned out of the direct passage-way through the casing, the king-bolt being shown in Fig. 10 moved to the doorway at one edge of the casing, so that one of the wings may be used for temporarily A portion a of the when closed by the door-wings, as shown in the figure. The king-bolt c is shown swiveled in the guide-arm at, which is pivoted at one: end upon a fulcrum u, attached to-the ceiling.

7). A curved'slot 10 extends through the ceil-, ing concentric with such fulcrum,and acu rved track a; is shown sustained adjacent to the slot by a beam o. A roller is journaled upon t e arm, and a socket in the top of the arm adjacent to the roller is furnished with knife;,

edges of to support a notched hanger a, which carries ball-races sustained upon the head of the bolt. upon the hanger, and the other is adjusted upon the king-bolt by a nut M, which is used to adjust the bolt vertically with the wings. A keyway w is shown in the king-bolt within the nut, and a lock-screw Q03 is inserted through the side of the nut in such keyway, by which the nut can be looked after any rotation. The nut forms an adjustable collar.

Fig. 1 shows the center pin at the bottom of the wings, provided with a vertically-movable bolt 0, fitted to asocket 0 in the floor, and another socket 0 is indicated by dotted lines in the position to which the lower pivot would be moved when shifted by the guide-arm, as shown in Figs. 9 and 10.

Figs. 16 and 17 show positions different from that of Fig. 10 into which the door-wings may be moved to clear the passage, Fig. 16, showing an arrangement of the curved slot 14 and the guide-arm u to place the wings all in one group within one side of the segmental casing. Fig. 17 shows two of the door-wings secured rigidly together and the intermediate wings folded flat upon their opposite faces, the whole being moved sidewise almost in a direct line across the center of the casing to place them against one of its segmental sides. In Figs. 16 and 17 the wings are shown in full lines in the center of the passage folded so as to extend one-half upon each side of the supporting king-bolt, which perfectly balances the load upon the bolt. With this arrangement no resistance is offered to the movement of the wings to a new position, asthey are suspended from the guide-arm, and the guide-arm is supported movably by the roller o When the bolt 0 is withdrawn from the floor-socket 0 and the wings folded together, as shown in Figs. 16 and 17, they may be readily pushed into the direction in which they are guided by the pivoted guide-arm u, the king-bolt moving through the slot u until arrested by the end of the slot, when the bolt 0 would be inserted in the floor-socket 0 which looks the center pin and holds the Wings in their new positions. During such shifting of the wings it is important to avoid any Wrench of the king-bolt, which is the sole support for the Wings, and I have therefore provided the hanger w, sustained upon the knife-edges '0 so as to rock readily upon the guide-arm. These knifeedges are disposed transversely to the guidearm and permit the wings to swing if pressed transversely to the slot 20 As there is no resistance to movement in the direction of the slot, the hanger does not need to rock in that direction; but the guide-arm is adapted also to yield in that direction by a peculiar joint with the pivot-pin u upon the ceiling of the casing.

The end of the guide-arm is formed with a flared socket, the small part of such socket One of the ball-races x is supported being fitted to the pivot-pin and the arm being thus adapted to twist in either direction upon the pin. It will be observed by reference to Figs. 1 and 11 that the guide-arm it occupies very little vertical head-room, and thus furnishes a means of shifting the Wings to an operative position in cases where the head-room is limited. The application of the braces to the hand-rails furnishes a means of securing the wings with very little additional mechanism, and the upper brace upon the wings reinforces the support which is furnished by the hand-rail braces, and thus renders the whole structure more rigid and less liable to derangement.

It is obvious that guide-bars precisely similar to the guide-rails can be used to brace the door-wings at any point in their height and that, if desired, a brace for the lower portion of the door-wing may be made similar to the upper brace shown in Figs. 6 and 7, although the construction of those figures is particularly adapted for an inaccessible part of the wing in which the pawl requires to be operated by a projecting rod.

Both of the methods for hinging the wings together which are shown in the annexed drawings are common, as is shown in patents already issued to me,and the particular method employed is immaterial to the present invention, as the guide-arm operates the same to shift the king-bolt and the supported wings whatever be their connection with one another and with the bolt. In like manner the operation of the braces is the same whether two of the wingsbe attached rigidly together, as shown in Figs. 2 and 17, or all the wings be jointed to their support, as shown in Figs. 10 and 16.

Having thus set forth the nature of the invention, what is claimed herein is 1. A revolving door structure having at the top a center king-bolt with wings suspended therefrom, and a guide-arm swiveled to the king-bolt and pivoted upon the ceiling of the door-casing to transfer the wings from an operative to an inoperative position.
